Building Regulations and Planning Permission

Building Regulation For Garden Room
The UK Government is responsible for the national policy on building regulations. “Building regulations exist to ensure the health, safety and welfare of people in the building and the energy efficiency of the building”. Building regulations are concerned with how a structure is designed, built and insulated.

Designing Your Garden Room
Garden buildings up to an internal floor area of 30 square metres are exempt from building regulations as long as the building isnt going to be used as sleeping accomodation. This leads many garden room companies to claim their products “comply with current building regulations” when in reality what they mean is “our buildings do not have to comply with building regulations”.
Base Garden Rooms comply with all current building regulations . Buildings that do not follow the latest building regulations, tend to have no or minimal insulation in their floor walls and ceilingsand do not incude vapour barriers or breathable membranes which can therefore reduce the life span of the building, causing the building to sweat in the summer and be inhabitable in the winter. Due to the fact that we do comply, our Garden Buildings are habitable all year round, are very efficient and therefore keep running and maintance costs to an absolute minimum for you the owner.

If you can answer “No” to all of the following four questions, your new garden room, office, studio or lodge will NOT require planning permission:

1 – Will the garden building stand forward of the principal elevation of your house, fronting the highway?

2 – Will the garden building along with other buildings and additions, occupy more than half the area of land around the original house? (When it was first built or as it stood on 1st July 1948)
